The Reborn Saint Wants to Do Fan Activities! Although I'm an Oppressed Noblewoman, I'm Being Dotingly Loved by My Beloved Prince!?

The protagonist, a modern-day person who was actively engaged in fan activities ("推し活"), dies in an accident and reincarnates as Elicia, the daughter of a duke in a fantasy world. Due to her black hair and black eyes (traits resembling her Japanese self), she is scorned as the "Daughter of Evil" and lives a miserable life. Deciding to hide her saintly powers and live in the shadows, her fate changes when she is helped by Crown Prince Reischelto at the royal castle. She declares, "I've found my favorite person in this world, too!" To earn money for her new "fan activities" (like supporting the prince), she secretly starts working as a charm-maker under a pseudonym. To her surprise, a man who sounds exactly like Reischelto shows up at her shop. The story follows her efforts as an ardent fan who is completely unaware that the object of her admiration is starting to dote on her intensely.
